My kids like my chicken pie (made with leeks, carrots, flour to make the sauce) but recently we had an M and S chicken pie and since then they are clamouring for chicken pie every meal time. They say they want mine (it's a matter of loyalty) , but I suspect they want it to taste like the M, and S one.
The M and S is really expensive.
How do I make one that tastes the same or similar? It doesn't appear to have any discernable vegetables and I'm mystified as to how they make the gravy.
Any ideas?
